A2:Concurrency broken with A5 and E16 in Derry b/n B507_S and A5. I think you've extended A5/E16 over the bridge to A40 but A5 misses this wp. All wps need to be renamed.Concurrency broken with A11 in Belfast b/n A6 and A24

If two named cross roads have different names but would have identical labels (Milford Parkway & Millville Parkway both would be MilPkwy), either add a 4th letter to a 3-letter part of one of the labels, or choose 3 different letters for that label.

B6:Split B178 into 2 wpsA24 should be moved to the center of the roundaboutSegment east of A22 is not indicated being B6 (OSM, GM, GSV)

B7:Split B8 into 2 wpsB10_N -> B10/B25

B8:B25 is off+X05 is off

B9:A3 -> A3/A26

B10:A25 -> A25_S

B12:A3 -> A3/A76

B14 / GlenBalSR:SkeRd is offSkeRd -> SkeEastRd ?SkeRd might be removed+X02 is off

B34/B131/B196:OSM suggests that B34 extends at east end to B131/B196 junction.GSV could be interpreted that B34 just extends to the junction west of the B131/B196 junction and that the section in-between is B196 or B131. The parallel road should be B196 too.I would go with OSM if you don't have an official source.

B34:BovRd is indicated being a B106 branch according to OSM and GSVA29 -> A29/A45

B35:KilRd_E -> KilRdKilRd_W -> KinRd or KicRdA4 -> A4/A45

B36:EshRd source? OSM inidcates Drumshancorick Road

B38:Split B101 into 2 wps

B39:A11: OSM and GM suggests it being B126; GSV 2008-2018 just indicates "(A12)" and "(M1)"Is B39 really concurrent to A52 here? If it's not signed, I would split the route.OSM shows a B39 branch off A52 at A52_W junction but I cannot find anything on GSVA52_W wp needs to be split into 2 wps if the B39 branch exists. If not, the wp should be at the western junctionOldBalRd should be moved a little bit because it's virtually one junction (overlapping)

Sorry, time was short, and addressing the concerns in the database was more important, IMV, than explaining.

Thanks for this review.

Like the Isle of Man, and Jersey, there's many places where OSM is wrong (albeit in an understandable way). I've also not included unsigned spurs, even if there are main routes that are unsigned (the inclusion of which is a general principle for the islands that speak English in NW Europe, based on the opinions of those there).
